Suspended Concrete Flooring
Description

The Speedfloor Suspended Concrete Flooring is a unique, composite floor of steel and concrete that makes light work of pouring anything from single level, to multi-storied structures. There is no propping required. Simply assemble the joists, add structural supports and you are ready to pour.

The Speedfloor Suspended Concrete Flooring is a proven performer in all types of construction, from steel structures, masonry buildings, poured in-situ or pre-cast concrete panels, to ICF, timber and cold formed steel frame construction. Manufactured from galvanised, high strength steel in a one pass roll-former, the frame is light enough to be manhandled into place for pouring. The ends are simply bolted to the joists which are then ready for transport to site with no propping or painting required. 

Slabs can be 90mm to 220mm in thickness. Minimum compressive strength of 25 mPa to achieve composite action is normally achieved within the first 72 hours of curing, depending on environmental conditions. 

The Suspended Concrete Flooring meets Australian and NZ composite structural standards and the NZ Building Code standards for fire and acoustic performance.

The suspended slab can be fire rated by applying the SPM method developed by Heavy Engineering Research Association (HERA) without additional treatment of the steel joists or fire-rated plasterboard ceilings.

Key Features
  • Requires no propping.
  • Reduces use of secondary steel, subject to structural requirements.
  • Joists can be manually positioned, reducing the need for cranage.
  • Provides a safe working platform during construction.
  • Services can pass through the pre-punched holes in the joist.

Frame is light enough to be manhandled into place for pouring. The ends are simply bolted to the joists which are then ready for transport to site with no propping or painting required. 

Slabs can be 90mm to 220mm in thickness. Minimum compressive strength of 25 mPa to achieve composite action is normally achieved within the first 72 hours of curing, depending on environmental conditions. 

The Speedfloor concrete floor system is suitable for all types of construction including:

  • Steel structures
  • Masonry buildings
  • Concrete poured in-situ walls & beams
  • Pre-cast concrete panels
  • ICF 
  • Timber framed construction
  • Cold-formed steel frame construction
Limitations on Use
  • Speedfloor should be used within the scope of the Load v Span calculator and design parameters set out in project specific Producer Statements issued by a Structural Engineer
  • Speedfloor is not suitable for use as a transfer floor or for cantilevered slab edge over 300mm (running parallel to the joist). See drawing SD8 for minimum slab distance required
Statement of Building Code Compliance

The Speedfloor Suspended Concrete Floor system meets Building Code Clauses B1 and B2 when used in accordance with the manufacturer's specification and project specific Producer Statements.

The Speedfloor Suspended Concrete Floor system is designed to comply with the following NZS and AS/NZS Standards to meet the requirements set out in the Building Code.

  • NZS 3404:Part 1 & 2
  • AS/NZS 4600
  • AS 1397
  • AS 2327 Part 0 & 1 
In-Service History

The Speedfloor Suspended Concrete Floor System was designed and developed in New Zealand over 17 years ago. Since that time, it has been used extensively throughout the country in numerous building applications including commercial mezzanines and mid floors, multi-level carparks, multi-level residential towers and single dwelling residential homes. The New Zealand office operates as the technical support base for global manufacturing partners operating in Australia, India, the United States and Europe.

Other Performance Attributes

The Suspended Concrete Floor System can be fire rating using gypsum board systems, protective coatings, or SPM (Slab Panel Method) as stated in the Slab Panel Method Product Manual.

The SPM method was designed and tested by HERA (Heavy Engineering Research Association), SCNZ and Auckland University. The SPM slab design forms part of Speedfloor's Producer Statements for every project using this system.
